Hill's Group: Interesting tidbits from FiveThirtyEight
http://fivethirtyeight.com/live-blog/march-15-primaries-ohio-florida-results-presidential-election-2016/There are some, mostly supporters of the Other Candidate, who are criticizing FiveThirtyEight for its predictions on MI, failing to understand that the polls are what they are and Nate & Co, make their predictions based on polls conducted by other people. There is some discussion of the MI result at the link.
The link is to their Live Coverage Thread. Scroll down to see what Harry Enten has to say about demographics-based predictions and just above that, a later post by Nate, showing those demographics. The results are mostly favorable to Hillary, although not nearly in the percentages that the polls show in some instances.
Please let these favorable predictions be true!

The southern vs. northern hypothesis.
The young vs. the olds.
The black vs. white hypothesis.
The open primary vs. closed primary hypothesis.
The rust belt hypothesis.
What I think all of us should take away from this primary season is that this shit is complicated, multi-factorial. Nobody has a crystal ball. Polling is really, really difficult in the best of times. And let's all understand that these are not the best of times. I don't pay much attention to the primary polls. But yup! They are still fun. So I don't blame folks for cheering on their candidate. I do it, too.
However, I believe that the only indisputable truth in getting Democrats into office is turnout.
Now, my primary vote won't make any difference now since I live in Michigan and I voted for Bernie. But we fight amongst each other at our collective peril. Only by working together to GOTV in November can we insure a win. And it isn't just about the White House -- let's make that clear as well.
Vote for the candidate of your choice, but for Christ sakes, vote Democratic in November.
As always, my best to you all in the Hillary group. May the best candidate win in November. We know it will one on the Democratic ballot. If we stick together.
we are on different sides in this primary divide! 
We have so much more in common than not. And we have absolutely zilch in common with the GOPers.
probabilities - not predictions. But still let the probabilities hold true!
